Abrahams says she and her partner put Kiesha in a shower to try to wake her and awoke the next day to find Kiesha was dead.

"We went down to the garage, he came back with a suitcase," Abrahams can be heard saying through uncontrollable sobs.

"And then we went to the bush, and then we went there, he didn’t want me to look."

Supporters in the gallery today cheered as Abrahams was sentenced to a maximum term of 22 and a half years in jail, with one yelling out "rot in hell" as she was led away.

Kiesha's paternal grandmother Liz Weippeart said she was happy with the sentence but the family's neighbour Alison Anderson described Abrahams as a "putrid dog" who deserved worse.

NSW Supreme Court Justice Ian Harrison reduced Kristi Abrahams' sentence by 10 percent for an early guilty plea and said the mother's crime was a "mid-range" serious offence when compared with other similar sentences.

Justice Harrison said Abrahams led a life "beyond most people's understanding" having suffered violence and abuse from a young age.

Speaking outside the court, a furious Ms Anderson raged at the judge's decision.

"What because she had a bad upbringing with abuse and stuff like that gives you the right to go take people's lives? I'm sorry, no," Ms Anderson said.
